United States Patent hfrce 3,3l,23 Patented Apr. 24, 1962 3,031,230 RETRACTABLE FOOTREST Richard C. Roe and Gthel W. Robbins, Rushville, 11111.,

assignors to Schnadig Corporation, Chicago, 111., a corporation of Delaware Filed Aug. 12, 1959, Ser. No. 833,193 6 Claims. ((11. 297-432) This invention relates to a retractable footrest, and more specifically, to a footrest structure adapted to be secured to a chair, sofa and the like for movement between retracted and extended positions.

An object of the present invention is to provide a footrest structure which may be connected to the underframe of a chair, such as a stuffed lounge chair, and which may be easily moved into extended operative position in front of the chair or into a concealed retracted position beneath the chair. Another object is to provide a retractable footrest which is adapted to rest on a floor surface when extended but which is raised into a suspended condition above the floor as it is urged into retracted condition. In this connection, it is a specific object to provide means for guiding the frame of the footrest structure into raised concealed condition and for holding the same in such condition when the footrest is retracted. Thus, even when the chair is shifted or lifted during cleaning or moving, the retracted footrest will tend to remain in fully retracted condition. A still further objectis to provide a footrest structure which is simple and yet extremely sturdy and compact in construction.

Other objects will appear from the specification and the drawings in which:

FIGURE 1 is a broken side elevational view of a chair equipped with a retractable footrest structure embodying the present invention, the footrest structure being shown in extended condition;

FIGURE 2 is an enlarged front elevational view of the extended and elevated footrest, the cushion of the footrest being partially broken away to illustrated internal structural features thereof;

FIGURE 3 is an enlarged longitudinal vertical sectional view of the footrest structure mounted upon a chair and disposed in extended and elevated condition;

FIGURE 4 is similar to FIGURE 3 but shows the footrest in fully retracted condition; and

FIGURE 5 is a broken perspective view illustrating structural details of the footrests structure.

In the structure illustrated in the drawings, the number generally designates a chair having legs 11 connected at their upper ends to an underframe 12. The chair is preferably an upholstered chair, such as the lounge chair in the illustration given, and the underframe of the chair must be spaced above a floor surface. It will be understood, of course, that aside from the features already mentioned, the chair may be any of a variety of types or styles and that if desired the footrest may be connected to a sofa, loveseat, etc.

Secured to the chairs underframe are a pair of parallel rails or tracks 13. The tracks are horizontally disposed and extend from the front to the rear of the chair, being secured at their ends to the underframe by screws 14. As indicated in FIGURE 5, the tracks are generally C-shaped in cross section with their open sides disposed in spaced opposition. However, at the ends of each track, the open sides are closed by front and rear stop members 15 and 16 which are welded or otherwise secured thereto.

The footrest proper is generally designated by the numeral 17 and includes a footrest cushion or platform 18 having a pair of transversely extending front and rear straps 19 and 20 secured to its undersurface. As shown in FIGURE 2, these straps have depending end portions or ears pivotally connected by rivets 21 to the upper ends of front and rear legs 22 and 23, respec tively. Thus, the legs are connected to the footrests panel or platform for pivotal movement in vertical planes with reference to said platform.

At their opposite lower ends, the legs are pivotally connected by transversely extending pins or rivets 24 to a U-shaped frarn 25 formed from a single piece of tubular stock. The U-shaped frame extends generally along a horizontal plane and has a pair of spaced rearwardly extending arms 26 and a transversely extending front connecting portion 27. The rear end portions of the arms are apertured for rotatably receiving a transverse bar 28 which is provided at its ends with a pair of hanger or rider elements 29. As shown in FIGURES 2 and 5, the rider elements 29 have laterally or outwardly turned upper portions disposed within the channels of tracks 13 and have vertical depending portions extending below the tracks or channels, rod 28 being secured to the lower ends of the depending portions. The rider elements also include rearwardly extending guide plates 30 (FIGURE 5) which are disposed within the channels and which maintain the tracks and rider elements in proper operative relation by resisting forces applied to frame 25 which might otherwise tend to move bar 28 into an angular position and thereby cause removal of the rider elements from the tracks.

A transversely extending U-shaped strap 31 hangs below tracks 13 and is provided with a pair of vertical side portions 32 and a horizontal intermediate portion 33. The upper ends of side portions 32 are welded or otherwise secured to the tracks between the front ends and the longitudinal midpoints thereof and, as indicated in FIGURES 1, 2 and 3, the intermediate portion 33 is spaced above a floor surface and is disposed at an elevation slightly lower than the bottom ends of rider elements 29. It will also be noted that the intermediate portion is slightly lower than the undersurface of the frame 25 adjacent rod 28. Preferably, the leading edge of the intermediate portion slopes downwardly and forwardly, as shown in FIGURES 3-5, for reasons which will appear shortly.

Referring to FIGURES 3 and 5, it will be seen that the front legs 22 of the footstool are arcuate in shape with the central portions curved rearwardly when the footrest is in an elevated condition. It will also be noted that the front legs are shorter than the rear legs so that when the footrest 17 is elevated, the supporting surface of panel 18 slopes downwardly and forwardly. The upper ends of both the front and rear legs are flattened to provide flat abutment surfaces 34- and 35, respectively which engage the under-surfaces of members 19 and 20 to limit forward pivotal movement of the legs and forward movement of the footrest 17 with reference to frame 25 when the footrest is raised. However, the upper front corners of the legs are rounded so as to permit rearward and downward movement of the footrest into lowered condition. Preferably, the front and rear legs are connected by rivets 24 to opposite sides of each arm 26 of the frame so that the front and rear legs will not engage each other and obstruct movement of the footrests 17 between raised and lowered positions.

Since the front legs 22 are shorter than rear legs 24 and since frame 25 slopes downwardly and forwardly when it is in the position shown in FIGURES 1 and 3, the center of gravity of the footrest 17 is disposed Well in front of a vertical plane equidistant between the rivet connections 24 for the front and rear legs, thereby providing a stable footrest when the same is in elevated condition. However, the footrest may be quickly and easily lowered by simply urging panel 18 rearwardly and upwardly until the center of gravity has been deplaced rearwardly a sufficient distance to cause the legs to pivot downwardly and rearwardly under their own weight and the weight of the panel. When the footrest 17 is fully lowered, the undersurfaces of straps or members 19 and 20 rest upon the tubular arms of frame adjacent the rear thereof, as indicated in FIGURE 4. The footrest may then be retracted by urging frame 25 rearwardly along tracks 13 until guide members engage stops 16 (FIGURE 4).

During rearward movement of the frame, legs 26 move into surface engagement with the intermediate portion 33 of strap 31 so as to cause an upward pivotal movement of the free end of the frame about rod 28. As retraction is continued, curved surfaces of the arcuate front legs extending below arms 26 engage the intermediate strap portion 33 to cause further upward pivotal movement of the frame and the collapsed footrest carried thereby. Finally, when the frame is in fully retracted condition, its front connecting portion 27 is disposed well above the level of the pivot rod 28 and the entire assembly is snugly disposed beneath chair 10. Since the tubular connecting portion of the retracted frame is then disposed between tracks 13 and is at substantially the same elevation as those tracks, the frame and collapsed footrest 17 are concealed from ordinary view, particularly when the structure is viewed from the front of the chair.

When the frame and footrests are retracted, as shown in FIGURE 4, a major proportion of the length of the curved front legs 22 is disposed behind the supporting intermediate portion 33 of strap 31. Consequently, the front arms of the retracted footrest assembly tend to resist forward sliding movement of the frame even when the chair 10 is moved about or even lifted or carried. On the other hand, the frame may be easily extended when use of the footrest is desired by simply reaching beneath the front of the chair, gripping the tubular connecting portion 27, and pulling that portion downwardly and forwardly.

When the footrest assembly is fully extended (FIGURE 3), the tubular connecting portion 27 of the U-shaped frame 24 rests upon a floor surface and provides rigid support for the elevated footrest unit 17. Thus, it is believed apparent that the structure of the present invention constitutes an extremely sturdy and durable footrest assembly which may be easily moved into extended and elevated position in front of a chair or into collapsed and retracted position beneath said chair.

While in the foregoing, we have disclosed an embodiment of the present invention in considerable detail for purposes of illustration, it will be understood by those skilled in the art that many of these details may be varied without departing from the spirit and scope of the invention.
